Question

The value of 6.67*10^-11 Nm^2/kg^-2 . what does it mean​

Answer 1

6.67E-11 N-m^2/kg^2 is recognized as the gravitational constant where

F = G M1 M2 / R^2

Putting in units:

F = N m^2/ kg^2 * [kg * kg / m^2] = Newtons

where F is the force between masses M1 and M2 separated by distance R
